To all 20/: cm 1' r, may concern Le it known that l, GUSTAV Bnmsc g, a citizen of the United States of America, end rcsh mi; of the borough of Brooklyn, county of Kings, an State of llcw York, have invented. cei- 11 new and useful Improvements in Universal Adjustable Pivots for Swinging Doors, of \vl'iich the following is a specificiiti n.

This invention relates to in'iprovements 1n universal adjustable pivots, and particularly such pivo for doors of granite inzmsoleums or other such peri'nenent structures exposed to the "121112 ts. Those doors {LS hcr tofcre constructed. v usually set on ebi'onze seddlc and swung inwmfdly, so that there exsted, because of the nature of the door end (po ed joint which would allow rain to beat or seep into the structure, and thereby gradually deteriorate the some and endanger its t the present invent on is to pted to sv... oute against permanent shut- 1 suit-able doors a universal edjustshlc p L, so that any inaccuracy in the drilling of pivot holes before the granite is may e corrected, and thereby establish close joi h tween the door aiudltreme. A e adjustment may also be used on a. door inward or on any other type of door. I

With this and other objects in view, my invention consists ofthe novel features, construction and arrangement of parts hereinafter more fully described and pointed out in the claims. I

In the drawings, Figure l. is c front elevation-cl view of a double door embodying my invention; 2 is e horizontal section oi? Fig. 3 is in vertical section thereof; .l ig. is an enlarged verticslecction of my universal ccljus'elile pivot; Fig. 5 is s. horizoi I. seem n of on the ig, is sec ional eretc e plain of universal adjustable sectional view of s of door bronie saddle modified in pivot; and, o modified is s and more per- JL'; .i

1 i 1 1 p provided g, e cundeo one as shown in or otherwise ltehly shaped, such as a the improper adjustment of the hinges, an

sseoi', 8. door 1 is shown for instance in Fig. 8, fitting in the jemb 2 of a door-frame, so that the same may freely swing and at the same time form v a tight joint when closed. The door il1ustrot-ed swings outwardly, but this is not do essefitizil to the operation of my invention. Holes are drilledin the platform 4 of the door and lintel 5 at either side thereof when there are two doors, and at one side when there is only one door, and bronze rings 6 '85 provided on their inner surface with teeth are secured by bubbitting or other suitable means into the said holes before the granite or concrete is set. The frame for the door is then set up iii-this form, and eccentric bronze rings 7 having their inner and outer surfaces toothed to correspond with the toothed inner surface of the bronze rings 6, are placed therein, and a second eccentric ring 8, having its outer surface to0thed, is

placed in the said ring 7. The exact pivot point for the door is then determined by arranging the said rings with respect to each other and with respect to the jambs of the door-frame, so that the recess 9, formed by the hole in the ring 8, coincides With the said pivot point. When the rings are so am ranged, the doors are set thereon, and bolts or pivots 10 provided in recess 11 in the door are slid into the same end secured in place by screws 12. u

In the form shown inFig. 7, disks 13 having apertures 14 therein ercsccured into the,

liutel and platform, before the same are set,

apertures and disks may be square (as shown), rectangular, polygonal, or other suitable shape, into which a plate 15 of corresponding shape is adapted to be fitted. When the structure is set up, the exact 'pivot 9 points are ascertained on the plates 14 and holes 1%; are drilled therein accordingly for receiving the bolts or pivotsBO of the door.

Where a saddle or e saddle and lintcl of a separate structure and material, for instance of bronze, are provided-for thedoor-frame, the holes for the rings or for the pivots, are drills-din the seperste saddlc and. lintel, as shown at 21 and 22 in Fig. 6. If desired, the bronze rings 8 or the'dislrs 13 may be made integral Withthe saddle and lintel of bronze with the same result, or in other Words, apertures corresponding in shape to the eccentric rings 7 and disks 1 lmey be provided in the saddle and lintel.
